A comfortable home is one of the advantages from using the SL 38 window system. Thermal insulation and air infiltration are key parameters in maintaining a sustainable climate inside.
The new SL 38 system offers three levels of waterproofing for maximum interior illumination. The depth of the profiles allows the use of double (HR++) as well as triple (HR+++) glazing, so as to achieve a Uw value of 1.4W/m²K similar to the CS 86-HI system.
High Uf = 1.6 W/m²K
Medium Class 2 (300Pa) / Class 5A (200Pa) / Class C3 (1200Pa)
Max 3000 mm
Min 72.5 mm
